3 Listen and Look Here is a list of key terms you will hear and see during the reading and video. Get to know them! Directions: Your objective in this activity is to earn 100 points. Choose any activities you wish and complete by the due date assigned. Complete the vocab exercises only if you fail the vocabulary quiz! This is a remediation assignment Activity Points 1. Complete a Frayer diagram for each word. Divide your diagram into the following categories: 100 definition, Sentence, Diagram, and Example. (Diagram is a labeled picture.) 2. Create a Vocabulary Booklet. Each page must have the term at the top, the definition at the bottom, 100 an example and an illustration in the middle with a sentence or description using the term. 3. Word Detective for all words. Use your textbook and a dictionary Do they provide the same 100 definitions? (Make a chart that has the word, definition from book and page #, definition from dictionary, name of dictionary and page #, and sentence using word.) 4. Complete a Vocabulary Log with all vocab words: (word, definition, and example or illustration) Create a rap, song, riddle, or poem including words and meanings. (25 points extra if you perform it for 50 the class) 6. Create and complete a crossword puzzle including all words. You MUST give clues or definitions for the 50 Across and Down Sections. You may not use the same clues or definitions as word search. 7. Create and complete a word search including all words. You MUST give clues or definitions. DO NOT list 50 the actual key word. You may not use same clues or definitions as the crossword puzzle. 8. Write an essay or story including all words. Only one word per sentence. Words must be used 50 correctly. Spelling and grammar will be considered. Essay/story must be at least 3 paragraphs long. 9. Create a detailed and logical concept or word map. Use linking words on the lines or arrows. Must 50 show relationship between words. Visit: or to obtain templates and link to websites to help with your assignment. VOCABULARY EXERCISES: Due November 10 VOCAB QUIZ:. Cellular Process : activities occurring at the cell level. Homeostasis: regulation and maintenance of constant internal conditions in an organism. Transport of molecules: method by which molecules are moved in and out of the cell. Phospholipid: molecule that forms the double layered cell membrane; consisting of a glycerol, phosphate group and two fatty acids. Fluid Mosaic Model: model that describes the arrangement and movement of the molecules that makes up the cell membrane. Selective Permeability: condition or quality of allowing some but not all, materials to cross a barrier or membrane. Diffusion: movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration. Osmosis: diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. Cellular Processes Unit Guide Page 3

4 Active Transport: energy-requiring movement of molecules across a membrane from a region of lower concentration to a region of higher concentration. Passive Transport: movement of molecules across the cell membrane without energy input from the cell. Concentration Gradient: difference in the concentration of a substance from one location to another. Energy Conversion: the process of transforming energy from one form into another. Reactant: substance that is changed by a chemical reaction. Product: substance formed by a chemical reaction. Photosynthesis: process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water. Cellular Respiration: process of producing ATP by breaking down glucose molecules when oxygen is present. ATP: Adenosine TriPhosphate- High energy molecule that contains, within its bonds, energy that cells can use. Aerobic Respiration: process that requires oxygen to occur. Anaerobic Respiration: process that does not require oxygen to occur. Fermentation: anaerobic process by which ATP is produced by glycolysis. Chlorophyll: light absorbing pigment molecule in photosynthetic organisms. Light-Dependent Reaction: part of photosynthesis that absorbs energy from sunlight and transfers energy to the light-independent reactions. Light-Independent Reaction: part of photosynthesis that uses energy absorbed during the lightdependent reactions to synthesize carbohydrates. Glycolysis: anaerobic process in which glucose is broken down into two molecules of pyruvate and two net ATP are produced. Cellular Processes Unit Guide Page 4

5 Recall and Review: ANSWER ALL THE QUESTIONS IN COMPLETE SENTENCES. Use the video and your textbook to help you answer the following questions in your binder. Chapter 3 (Section 3) 1. Draw, color and identify the following structures of the cell membrane: carbohydrate chain, cholesterol, phospholipid bilayer, transport protein. 2. State a function of each type of molecule that is embedded in the phospholipid bilayer: Carbohydrate chain: Cholesterol: Phospholipid bilayer: Transport proteins: Chapter 3 (Section 4) 3. Explain what a concentration gradient is and what it means for a molecule to move down its concentration gradient. 4. Compare and Contrast passive and active transport.
